My car wont start :/

Hi there, so my car was working fine yesterday then this morning I try to start it there is no dash lights, no electrical working what so ever, when I try start it nothing not even a sound.

ive jump started it twice with no change whatsoever in the situation.

so I googled it. Lots of people say battery bla bla but the only answer I have come across that sounds legit is a fuse. Ive checked the fuses and can only tell by the small ones if they blown or not but they all fine. The larger ones im not so sure about, can you help? Or do you know what the problem is?
